MARTIN KILLIAN, OF'GENTRAL CITY, COLORADO,

TOOL FOR MINERS AND BLASTERS USE.

SPECIFICATION forming part of Letters Patent No. 572,808, dated December8, 1896.

Application filed August 11, 1896. Serial No. 602,407. (No model.)

To all whom it may concern.-

Be it known that I, MARTIN KILLIAN, of Central City, in the county ofGilpin and State of Colorado, have invented a new and Improved Tool forMiners and Blasters Use, of which the following is a full, clear, andexact description.

- The object of the invention is to provide a tool especially adaptedfor miners use which will combine in one article knives arranged forsplitting the fuse or. for cutting the fuse into lengths, together witha device for fastening the caps on the fuse, a cutter for any kind ofwire, and a knife and punch, the tool being as compact as an ordinarypair of pliers and may be carried in the pocket with the greatest ease.

A further object of the invention is to so construct the knives thatthey may be readily removed from the tool in the event they shouldbecome dull, broken, or otherwise injured. The invention consists in thenovel construction and combination of the several parts, as will behereinafter fully set forth, and pointed out in the claims.

Reference is to'be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the tool. Fig. 2 is a section throughthe jaws of the tool, the said jaws being closed; and Fig. 3 is a detailperspective view of one of the knives removed from the tool.

In carrying out the invention the tool in its entirety is shapedsubstantially as a pair of nippers or pliers, embracing two members Aand B, each member comprising a body 10, a handle 11, and a jaw 12, thebody portions of the members being of less thickness than the handlesandjaws, so that the body portions may be mounted to turn loosely one onthe other, being connected by a pivot-pin 13 or its equivalent. The jawsmay be in any shape, but are preferably made tapering longitudinally andare more or less triangular in crosssection, as shown in Fig. 2, theirwider or base portions being arranged to come in contact. In the meetingface of each jaw a longitudinal groove 14 is produced, and these groovesare preferably segmental in crosssection and are arranged to registerwhen the jaws are closed. Above the groove in the upper jaw and belowthe groovein the lower jaw a longitudinal T-slot 15 is produced,communicating with the segmental grooves 14, and in each of these slotsor channels 15 a substantially T-shaped knife 16 is introduced, theshank portion of each knife extending into the segmental groove 14 ofthe jaw to which the knife is applied, and the shank portion of eachknife is made tapering, being sharpened to form a cutting edge 17 atthat part which enters the grooves. The knives are so placed that whenthe jaws are brought together the cutting edges will be substantially incontact. The knives are held in place by means of set-screws 18 or theirequivalents, whereby either knife may be expeditiously and convenientlyremoved and replaced. In the meeting faces of the said jaws, betweentheir centers and the body portions 10 of the members of the tool, atransverse segmental recess 19 is produced, across which recesses theknives 16 are carried, and the fuse that is to be cut in lengths isentered between the jaws at the transverse recesses 19, enabling thefuse to be quickly cut as the jaws are closed without crushing the fuse.The recesses 19 are adapted to register when the jaws are closed. Theouter end portions of the knives are employed for shredding or slittingthe end portion of the fuse.

A semicircular recess 20 is made in the inner edge of each handleportion 11 of the tool, and the wall of each recess is crimped, as shownin Fig. 3. These recesses 20 are adapted to receive between them the capwhich is to be fastened to the fuse, and as the handles are broughttogether the cap will be crimped firmly to the fuse. a pocket 21 madelongitudinally in its inner edge, and at the rear end of one handle apointer 23 is pivoted, adapted when not in use to enter the pocket ofthat handle, and this pointer is employed for making a hole in thepowder for the introduction of the cap and the fuse, while a knife-blade22 is pivoted to the opposite handle and when not in use will enter thepocket in the same. Openings 24 are made in the body portions of themembers of the tool to receive a strand of wire for the purpose ofenabling said strand to be out,

Each handle hasbut this form of wire-cutter does not differ from theform ordinarily used in connection with pliers or like tools.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A tool for miners and blasters use, comprising thepivoted jaws and handles, the jaws being provided with longitudinalgrooves in their meeting faces and knives secured to said jaws andhaving their cutting edges in the same plane as the meeting faces of thejaws, whereby said edges contact when the jaws are closed, the jawsbeing further provided with transverse recesses or openings across whichthe knives extend, as and for the purpose set forth.
